Abstract
The utility model discloses a new piston assembly of an internal combustion engine. The utility model is characterized in that a piston body (1) is provided with a gas ring groove (2), the gas ring groove (2) is provided with an upper locating pin (4) and a lower locating pin (5) which are up and down staggered, a gas ring (6) and a gas ring (7) are contacted in surface in the gas ring groove (2), an opening of the gas ring (6) is corresponding to the upper locating pin (4), an opening of the gas ring (7) is corresponding to the lower positioning pin (5), and the openings of the gas ring (6) and the gas ring (7) are positioned in the staggered mode. In this way, the utility model avoids the leakage phenomenon of the piston assembly, the power can be enhanced, the oil consumption can be lowered, and the service life can be prolonged.
Description
The utility model relates to a kind of piston assembly, is a kind of piston assembly that moves reciprocatingly in the cylinder of internal-combustion engine that is applicable to particularly.
At present, the internal combustion engine assembly of using always on the market has the multiple tracks compression on piston main body, a compression ring that opening is arranged all is housed in each compression, owing to have certain distance between each compression, so compression ring wherein also has at interval, air-flow can be scurried out by compression ring opening and gap thereof when pistons work, causes gas leakage, especially the gas leakage of compression ring wearing and tearing back is more serious, influenced the pressure of internal-combustion engine greatly, the power of internal-combustion engine is reduced, oil consumption increases.The purpose of the utility model is to provide a kind of improved internal combustion engine assembly, has avoided gas leak phenomenon, even being worn also, compression ring can not leak gas, thus the working life of having improved compression ring.
For achieving the above object, the technological scheme that the utility model is taked is: place the twice compression ring in one compression of piston main body, make it tight plane contact, and the opening staggered orientation, composition ring formed, like this, not not at interval, wear the gas passage between the compression ring, when compression ring is worn the opening increase thereby stopped up, can not produce gas leak phenomenon yet, ensure sealing effect.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Fig. 1 cuts open figure for the utility model structure partial
In Fig. 1, have compression 2 and pin-and-hole 3 on the piston main body 1, the last locating stud 4 that is provided with up and down in the compression 2 and staggers reaches locating stud 5 down, compression ring 6 and compression ring 7 be closely contact in compression 2, its surface of contact is the plane, and compression ring 6 openings are corresponding with last locating stud 4, and the opening of compression ring 7 is corresponding with following locating stud 5, the opening of compression ring 6 and compression ring 7 is staggered, not on same vertical line.
Because the utility model is provided with two compression rings in compression, under the prerequisite that ensures power of IC engine and intensity, realize the utility model, can be on the basis of former piston, reduce compression quantity and widen compression, for example: the internal combustion engine of existing two strokes and four-journey all has the multiple tracks compression, an opening compression ring is arranged in the per pass groove, realize the utility model structure, can all change two strokes into widen compression with the internal combustion engine of four-journey, in two staggered up and down locating studs wherein are set, with two corresponding being positioned in the compression of compression ring.
Show that through test for several times use the more former piston assembly power of this novel piston assembly to improve 15%, oil consumption reduces by 10%, in addition, because the compression ring wearing and tearing strengthen the compression ring opening, also do not influence the sealing effect of piston, thereby can prolong the working life of compression ring greatly.
Claims (1)
1, a kind of internal combustion engine assembly, form by piston main body (1) and compression ring (6), compression ring (7) etc., have compression (2) and pin-and-hole (3) on the piston main body (1), it is characterized by: be provided with the last locating stud (4) that staggers up and down in the compression (2) and reach locating stud (5) down; Compression ring (6) and compression ring (7) be closely face contact in compression (2), and the opening of compression ring (6) is corresponding with last locating stud (4), and the opening of compression ring (7) is corresponding with following locating stud (5).
